Question

pls help me urgent give me full method

Answer 1

Answer:

x = 75 degree

y = 105  degree

Step-by-step explanation

angle DCB = 180 - 75 = 105 degree ( sum of opposite angles in a cyclic quadrilateral is 180)

BF is a straight line so,

x = 180 - 105 = 75 degree (BF is a straight line so their sum equals to 180)

y =  180 - 75 = 105 degree ( sum of opposite angles in a cyclic quadrilateral is 180).
